214A878AFFACFFBEC9F16F63D17AC2D8.taxon	discussion	Comments: — This species could be confused with B. rosmarinifolia E. L. Cabral & Bacigalupo, another endemic species from “ campos rupestres ” between 1100 and 1300 m elevation, in Minas Gerais. However B. rosmarinifolia can be differentiated due to its linear leaves and involucral bracts, which are rigid and oriented towards the apex.	en	Miguel, Laila M., Souza, Elnatan B., Cabral, Elsa L.

214A878AFFA9FFBCC9F16DCCD712C441.taxon	distribution	Distribution and Habitat: — Borreria psyllocarpoides occurs in Brazil, in the states of Goiás and Minas Gerais, along the margins of the river Paranaíba, in the Canal do São Simão. This area is included in the “ cerrado ” vegetation (Fig. 5).	en	Miguel, Laila M., Souza, Elnatan B., Cabral, Elsa L.

214A878AFFA9FFBCC9F16DCCD712C441.taxon	conservation	Conservation status: — In this study we analyzed specimens from Canal do São Simão, a narrow canyon of 600 m wide, formed by the Paranaíba River, and representing the natural limit between the states of Minas Gerais and Goiás. These specimens were collected by Duarte in 1970 and 1972. In 1978, the São Simão Dam began to operate, which meant that the Canal and the original City of São Simão were flooded. Therefore, following the IUCN criteria (IUCN 2012), this species is data deficient (DD) because we consider that information about its current distribution is lacking.	en	Miguel, Laila M., Souza, Elnatan B., Cabral, Elsa L.

214A878AFFA9FFBCC9F16DCCD712C441.taxon	etymology	Etymology: — The specific epithet refers to the similarities of this new species with Psyllocarpus schwackei K.

214A878AFFA9FFBCC9F16DCCD712C441.taxon	discussion	Comments: — Studied specimens were formerly identified as Psyllocarpus in different herbaria and probably the most similar species is Psyllocarpus schwackei which also occurs in Minas Gerais state, in the Serra do Espinhaço (Kirkbride, 1979). However, B. psyllocarpoides differs from P. schwackei mainly by the corolla 3.5 – 3.7 mm long, white, glabrous throughout, the capsule with septicidal dehiscence from the apex and both cocci dehiscent without a persistent septum, while in P. schwackei the corolla is 3.8 – 6.1 mm long, blue, externally minutely and densely papillate, internally glabrous, and the capsule dehiscent from the apex downwards along the edge of the septum which is persistent, entire and erect, and both cocci are free.	en	Miguel, Laila M., Souza, Elnatan B., Cabral, Elsa L.
